I'm hoping someone here can shed some light on this.
My brand new MacBook Pro (MBP) 13" (no touch-bar) running High Sierra, decided last week to start playing up. I was working normally about to send an email from Mac Mail, when the rainbow disc showed up spinning forever! Then suddenly the MBP fan started revving up until at one point the MBP just switched off and tried to restart. It rebooted fine to the login screen. I logged in, or at least i tried, simply because at around 50% the progress bar decided to slow down to the point that at around 75% the MBP fan just started revving again until the MBP restarted again. This process repeated itself for about 5 to 6 times until i decided to force the MBP off, holding the power button for 5 secs.
I have tried everything under the sun:
1) Safe boot - same thing happens (i am referring to fan start revving up, screen goes black, then reboots)
2) Recovery boot to:
a) run Disk Utility to repair disk (which btw is encrypted APFS) - same thing happens
b) run Terminal to repair disk - same thing happens
c) re-install the OS - was going well until..... same thing happens
d) run Disk Utility to take an Image of the drive - can't do it all at once, so tried folder by folder.... and at some point guess what? Same thing happens.
3) Installed OS on an external drive, booted form there, tried to access the internal drive to backup my docs & data. a) So it worked for some but not for others - and what i mean by the latter is that as soon as i try to copy some files or particularly some folders the same thing would happen.
b) From what i read on the net, it seemed like an issue with the user profile and access rights, so using Terminal I cleared and set the access rights on the folders to a+rwx (had to do it folder by folder), and i managed to copy most of the data.
c) Just as I was almost complete, the same thing started to happen consistently every time i try to boot up to the external drive. Now it just wont do so. It does the same process of hanging and rebooting not allowing me to back up the last few items.
4) So i reverted to Target Disk Mode to try to access the drive from my old MacBook Air (MBA).
a) I set the MBP to TDM using T when powering up - managed that.
b) I purchased a USB-C to USB-A cable that supports TDM, and connected the two machines.
c) I tried accessing the MBP drive from Finder on the MBA - didnt show up.
d) So I stared Disk Utility on the MBA and here is where I am stuck - see attached screenshot. I just cannot get the Macintosh HD volume to mount. Even First Aid doesnt work - i get the following error:
How do I proceed from here? All I am trying to do at this point is access the internal drive of the MBP to take a full backup before taking the MBP back to Apple as it is still under warranty (just a couple of months old!).
Thanks in advance.
